Not gummy bears, but I've gone through various airports with cream filled chocolates, tootsie rolls, reeses peanut butter cups, snickers, milky ways, most candies.

Also just this weekend through SNA my companion sent through a styrofoam take-out container with BBQ ribs, mashed potatoes, macaroni and cheese, and rolls all fresh from the restaurant. Nobody said a word or gave it a second glance.
